The present article describes the recent role of polymers as carriers for delivery of drug at target site to extending its release. These polymers are widely used in delivery due to their inherent characteristics such as biocompatibility, biodegradability. Chitosan and Eudragit are choice of drug in extended release matrix tablets. Chitosan is an amino polysaccharide polymer which is biodegradable, biocompatibility and nontoxic nature. Due to its cationic nature, Chitosan form complex with anions like Eudragit giving rise to polyelectrolyte complexes. Chitosan enhances the dissolution of poor soluble drugs. Similarly Eudragit polymers are also copolymers derived from esters of acrylic and methacrylic acid and have large number of applications in extending drug delivery. This article reviewed the role of Chitosan and Eudragit in controlled release drug formulations. Also, the article included role, property and uses of Chitosan and Eudragit and their use in different drug delivery system for various therapeutic...

Tuberculosis caused by multidrug-resistant (MDR) and extensively drug-resistant (XDR) Mycobacterium tuberculosis (MTB) strains is a growing problem in many countries. The availability of the complete nucleotide sequences of several MTB genomes allows to use the comparative genomics as a tool to study the relationships of strains and differences in their evolutionary history including acquisition of drug-resistance. In our study, online resources for comparative genomics analysis between strains by using databases such as MGDD (Mycobacterial Genome Divergence Database), Biohealth base, GenomycDB, Mycobacterium tuberculosis database, and TBDB (Tuberculosis Database). Taken together, this study reveals that strain-specific variations in protein expression patterns have a meaningful impact on the biology of the...

With exponential advancements in healthcare and pharmaceutical sciences, Peptidomimetics have emerged as essential tools in the designing and development of novel and improvised therapeutics. The peptidomimetic based drugs are designed with the aim of overcoming the shortcomings of natural peptides and proteins. Thus, peptidomimetic therapeutics possesses increased efficiency, stability and overall better pharmacokinetic properties. This review paper outlines the applications and the underlying principles of peptidomimetic based therapeutics in various diseases and issues related to healthcare. Recent advancements in the development of peptidomimetics for Cancer therapy, Renin inhibition, HIV drugs, Analgesics, anti microbials and anti viral drugs have been discussed. Additionally, the applications of peptidomimetics in anti oxidants, anti malarial drugs, blood filtration membranes and as fibrinogen antagonists have also been...

Middle East Respiratory Syndrome (MERS) is viral respiratory illness that was lately recognized in human. It was first testified in Saudi Arabia in 2012 and has since spread to numerous other countries, as well as the United State. Record people well-known as infected with MERS-CoV developed numerous acute respiratory illnesses, including fever, cough and shortness of breath. Middle East Respiratory Syndrome (MERS) is an illness initiated by a virus (more specifically, a coronavirus) called Middle East Respiratory Syndrome Coronavirus (MERS-CoV). Around 3 to 4 out of every 10 patients reported with MERS have died. The biggest known outbreak of MERS outside the Arabian Peninsula occurred in the Republic of Korea in 2015. The outbreak was allied with a traveler returning from the Arabian Peninsula. MERS-CoV has spread from ill people to others through close contact, like caring for or living with infected person. MERS can affect everyone. MERS patients have ranged in age from younger than 1 to 99 years old. No vaccine available against MERS. The U.S. National Institutes...

Infectious diseases are among the most important common diseases worldwide that bring stupendous costs for human community. Medicinal plants are considered a rich source of antimicrobial agents and therefore can be used as antimicrobial remedies because of producing secondary metabolites. This article was designed to review the effective medicinal plants on fungi and fungal disease. In this study, the relevant articles published in Persian and English languages were searched for in the databases Magiran, Iranmedex, Irandoc, PubMed, Scopus, SID, Web of Science, and Science Direct using the search engine Google Scholar. To maximize the comprehensiveness of the search, the general terms antimicrobial, dermatophyte, mycotic, Iran, and anti-Candida as well as their Persian equivalents were used. AND and OR were used for combining searches. Medicinal herbs such as Zataria multiflora, Thymus vulgaris, Thymus kotschyanus, Punicagranatum L., Rosmarinus officinalis L., Matricaria chamomilla L., Urtica dioica L., Mentha piperita L. and Salvia officinalis L., Thymus vulgaris, Salvia officinalis, Eucalyptus globulus, Mentha piperita, Oliveria decumbens, Echinophora Platyloba, Thymus eriocalyx and Thymus X-porlock, Achillea...
